The Kazoobie Kazoo is the best plastic kazoo you can buy. We use the highest grade materials and every part of our process is "Made In The USA." Our resonator material is very durable and the caps are pressed in using 100 lbs. of pressure. Caps are VERY difficult to remove. Our kazoos have been safety tested and approved for children ages three and up. Top-shelf dishwasher safe, hand dry. Assorted Colors.
